[Poul-Henning Kamp]

Summary:

   Write Caching:
	Drive says "I have written your data" when it hasn't.
	(A bad thing!)

   Has not by definition anything to do with:

   Tagged queueing:
	Ability to reduce transaction latency by sending more than one
	request to the drive at a time.  The request may be handled out
	of order by the drive.
	(A good thing!)

and:

   ATA != SCSI.
